60: SARAH MCLACHLAN Canadian Sarah McLachlan is best known for her emotive, glacial ballads, but she complements her songwriting with an impressive sideline in charity work. The 47-year-old was signed to Vancouver-based label Nettwerk while still at college, before she had even written a single song. Her career peaked with Grammy-winning 1997 album Surfacing. Since then she has continued to write and has raised a staggering sum, in excess of £20m, for various charities.
